We bought Alto - k10 on Dec’11 because of maruti brand & fuel efficiency but to our surprise the car gave only 8km/l with ac & 10km/l without ac & front tyres were almost like of a 50000 kms run car in just 6 months of purchase. We complained the same to Hero honda chowk maruti service centre from where the car is bought & to maruti pasco at 18 sector Gurgaon also but to no use.
They just give excuses & always ask to let the car there for checking which we did for almost 7-8 times but after repeated checks nothing happened. they even not changed the tyres but only changed the position of tyres (i.e back tyres to front & vice versa) & some tuning after which the car started to give the average of 14km/l though very less then claimed by company. they said that car is okay & every product is different.
After we stopped following up & thought like we are cheated & friend told us to do a paid checkup & full service which almost cost us Rs.15000/- and after that the car is working fine. the conclusion is that maruti is an established & there customer base is so high that they doesn’t care any more. my personal opinion is that never go for Maruti in first place if you have other options. And also the hero honda chowk service centre workers are also arrogant.
